OIL BIJ'RNEB.

Application 'flled August 20, 1925. Serial No. 51,435.

This invention relates toimprovements in oil burners. An object of the invention is to provide a, Simple, efiicient and compact burner constructionwhereby a minimum of oil is consumed to give the maximum ofheating effect. I

Another object resides in the structural means whereby the oi air are most thoroughly mixed to produce the maximum combustion.

A further object concerns the provision of structural means whereby-flames generated are most efliciently directed to cause the heat- 'ing of water or other liquid in the burner.

A still further object-concerns the provision of simple and efiicient means whereby the oil is preheated;

The invention is illustrated in the drawings, of which- Figure 1 is a side elevation partly in tion of thedevice Fig. 2 is a sectiontaken on the line 2-2 of'F1g.3; r

The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and inthe character of the materials used may be adopted without departing from the spirit of the invention as set forth in the appended claims. 7

In its general aspect the invention comprises a burner having a frame, a supporting ring mounted thereon above the frame, an,

. adjustable air shutter between the supmrtp g ing ring and the frame, an oil cupor wl supported from the frame, anoil evaporatwithin the bowl, an air dethe evaporating plate an air casing attached to the bottomof-the bowl, and a central oil column extending u wardly from the bottom of the bowlan through which the oil passes to be preheated, said central column acting asa conduit for additional air and having at its top air and flame deflecting ,steam and pan means whereby the flame is guided and further mixed with air. i

'In the preferred form of the invention shown 1n the drawings, the burner is suitably supported within the 'furnace'on a plate therein. Around this shell I provide a slid- 'able ring 16 having apertures 17 therein adapted t0 be aligned with the apertures 15 whereby air maypass from beneath the burner through these apertures to the furnace enclosure above the burner, withoutv plies an passing through the flame. This su he ring additional air regulating means.

16 may be manipulated by means of a finger piece 18, shown in Fig. 2.

On the upper'end of the shell 14 I mount a sup rting ring 19. Screw bolts 20 connect t e supporting ring 19 with the base plate 13 and hold the shell 14 in place.

Suitably supported on the ring or plate 19 is an oil bowl 21 adjustably supported by means of bolts 22 at three points along its periphery with respect to the ring 19. This oil bowl, on its bottom, is provided with an asbestos gasket 23 against which a water 24 is disposed. A pipe 25 feeds water to the pan 24. A hollow head 26 is suitably fastened to the bottom of the bowl 21. To this head is threaded a hollow cylinder 27 extending upwardly fromthe. center of the v bowl. At its upper end this cylinder is provided with a metallic ring 28, partly closing the same. The bottom of the head 26 is disposed above the bottom of'the bowl 21 by reason of legs 29 (see Fig. 4). The bottom of the head is closed by a ringlike In 30. The inner edge of this plug is threadablv engaged by an inner cylinder 31 provided with a plurality of perforations 32 throughout its periphery' at definite levels. Screwed into the bottom of the bowl 21, and lying within the cylinder 31, is a tube 33 extending up through the ring or plug 28 and having a clamping ring 34 threadably engaged with its upper end and bearing against the upper surface of the. plug 28. The plugs 28 and as shown particularly in Figure 6 are provided with inner longituthe level of the opening in this dinal grooves 34 which pemit the oil vapor .which is generated within the column to es-' cape and mix with the air deflected outward-' ly bythe deflector plate 36. At the edge of plate 36 the mixture ignites. A deflector head 35 is mounted on the upper end of the cylinder 27, and suitably spaced above this deflector head 35 is a deflector plate 36 spaced from the head 35 by means of screws 37 and spacing sleeves 38. The upper end of the tube 33 opens beneath the plate 36. The lower end of the tube 33 opens below the bottom of the water pan 24. A clamping nut 39 holds the water pan 24 against the asbestos gasket 23. This nut engages the lower threaded end of the tube 33. The upper end of the cylinder 31 is open beneath the plug 28. A plurality of pipes 40 extend through the bottom of the bowl 21 and open into the chamber formed within the head 26 and between the cylinders 27 and 31. These pipes admit oil within these cylinders. The oil will rise within the head 26 until it reaches a,level corresponding to the perforations 32 in the cylinder 31,

where'it will pass through, passing down within the cylinder 31 to the bottom of the bowl beneath the head 26. It will then spread out beneath an evaporatin plate 41, which is shaped substantially con orming to the contour of the bottom of the bowl and The ring on its 42 between its inner periphery and the head 26, and between its outer periphery and the bowl 21 oil passages 43 are formed. A pipe 41 is disposed-in the side of the bowl 21, just above the level of the top of the evaporating plate 41, so that if the oil rises-to pi e it will overflow from the pipe and can be led to any desired location.

Along the lateral walls of the oil bowl, intermediate the bottom and the top thereof,

are dis osed a pluralitof air openings such as 44 see Figs. 1 an 2). These openings are of ample dimensions. Adjustably suported on screws 45 on a shoulder 46 with- -m the oil bowl 21 is a deflector rin 47 which extends downwardly and outwar ly within the bowl in front of the air opening 44 so j that air. passing therethrou h will be drawn downward on to the top 0 the evaporating plate 41. The evaporatin plate 41 is also adjustably supported on t e bottom of the bowl 21 by means .of adjustable screws 48 (see Fig. 4).

In the operation of the device the evaporating plate is adjusted at the, proper height above the bottom of the bowl. The deflector plate 47 is likewise adjusted; the oil bowl itself is adjusted in the supporting ring 19, and the air 0 enings 15 and 17 are properly registered eit er full or partly, as desired. Oil is then introduced into the pipes 40 and whence it will pass down along the inner surface of the tube 31 and flood the bottom ofthe bowl, rising through the openings 42 and 43, preferably the opening 43. The oil is then ignited, and. as it heats the apparatus the oil flowing in through the pipes 40 will be vaporized between the cylinders. 27 and 31. The vapor will rise between these cylinders, whereas the oil liquid will flow through the apertures 32. The oil vapor will rise to the top of the cylinder 31 and then pass down between it and the tube 33. Preferably this upper heating action on the oil will vaporize practically all of it, and most of the oil vapor will pass up between the inner periphery and the evaporator plate 41 and the edge of the head 26 through the passage 42. lVhat oil is still liquid will flow out through the passage 43 on the top of the evaporator plate. The oil evaporated becoming ignited on top of the plate 41 will mix with the air which is drawn in through the openings 44 and deflected downwardly by the plate 47. Thisflame will pass upwardly and be deflected outwardly by the head 35. At this point, just beyond the top of the head 35, it will be mixed with a portion of air which rises through the top and is deflected by the plate 36. If further air is needed within the furnace above the burner it can be admitted by adjusting the apertures 15 and 17 as above mentioned. This air will be drawn up from beneath the burner through the apertures into the furnace chamber around and above the burner. As the; air passes up from beneath theburner, along theedge of the air openings 44. which by this time has become so heated that the water is boiling, it will draw some of the steam or water vapor with it and this steam will pass in with the air to mix with the oil vapor.

Itis found that by providing a central oil preheating column, by providing an evaporator plate disposed in the manner described above the bottom of the oil bowl, and by admixing the air and steam with the oil in the manner above mentioned, a most eflicient combustion is effected and a very hot flame is produced. This flame is properly directed by the construction of the apparatus to effect the utmost efliciency in the heating by whatever medium the system may emtom of the cup, a central air passage in said column extending to the top thereof, an air 7 deflector plate at the top of the column, a flame deflector plate at the top of the 'column, the side of the cup provided with a plurality of air passages, and a deflector ring supported within the cup to deflect the air downwardly onto the oil evaporating plate.

2. An oil burner which comprises an oil cup, a central oil heating column therein,

said column comprising a plurality of spaced cylinders forming oil passages, one of said cylinders disposed within another and provided with apertures intermediate its height to permit the oil introduced between the cylinders to flow therethrough at predetermined levels.
